In 1707, Daniel Hayes, then aged twenty-two, was captured by the indigenous people and carried off to Canada. The capture was witnessed, and a rescue party raised, but the group did not catch up with the captors. He was tied up each night, and bound to saplings. It took thirty days to reach Canada, at which point Hayes was forced to run the gauntlet. Near the end of the gauntlet, he hid in a wigwam to avoid an attempted blow by a club. The woman in the wigwam declared that the house was sacred, and having lost a husband and son to a war, adopted Hayes as her son. He remained for several years, attending to the woman. Eventually, he was sold to a Frenchman, who learned that Hayes had skill as a weaver, so put him to work in that business. Hayes managed to earn enough to buy his freedom after two years. He then returned to Simsbury, settled down on a farm and married. He became prominent, both in civil affairs as well as the church at Salmon Brook (now Granby).[3]

The first unauthorized coins minted in the American colonies, and the first in Connecticut, were struck by Dr. Samuel Higley in 1737 from copper mined from his own mine. The coins, including the Trader's Currency Token of the Colony of Connecticut were minted in North Simsbury, now called Granby.[4] These coins were made of pure copper, which is very soft. Consequently, there are very few in existence today. The first coins were inscribed with a value of three pence. Later versions carried the phrase "Value me as you please."[5]
